Operating at \u003cstrong\u003e10.525 GHz\u003c\/strong\u003e, it uses Doppler radar technology to reliably detect moving objects across a range of \u003cstrong\u003e20+ meters\u003c\/strong\u003e — all without physical contact. Whether you're building a security system, smart door controller, or automation project, this module delivers consistent, accurate results even in demanding environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow It Works\u003c\/h3\u003e\n\u003cp\u003eBased on the \u003cstrong\u003eDoppler principle\u003c\/strong\u003e, the module continuously emits microwave signals. When those signals strike a moving object, the reflected frequency shifts — and the module detects that change. If an object is stationary, the reflected frequency matches the transmitted frequency and no trigger occurs. This makes the HB100X ideal for distinguishing genuine motion from background interference.\u003c\/p\u003e\n\n\u003ch3\u003eKey Advantages Over Other Detection Methods\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNon-contact detection\u003c\/strong\u003e — no physical interaction required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnvironment-independent\u003c\/strong\u003e — unaffected by temperature, humidity, noise, air, dust, or lighting conditions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrong anti-RF interference\u003c\/strong\u003e — stable performance in electrically noisy settings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow output power\u003c\/strong\u003e — safe for everyday use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong detection range\u003c\/strong\u003e — detects movement at distances exceeding 20 meters\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eTransmitter\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransmission Frequency: \u003cstrong\u003e10.525 GHz\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eFrequency Setting Accuracy: 3 MHz\u003c\/li\u003e\n  \u003cli\u003eOutput Power (min): 13 dBm EIRP\u003c\/li\u003e\n  \u003cli\u003eOperating Voltage: \u003cstrong\u003e5V ± 0.25V\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eOperating Current (CW): 60 mA max \/ 37 mA typical\u003c\/li\u003e\n  \u003cli\u003eHarmonic Emission: \u0026lt;–10 dBm\u003c\/li\u003e\n  \u003cli\u003ePulse Mode Average Current (5% DC): 2 mA typical\u003c\/li\u003e\n  \u003cli\u003ePulse Width (min): 5 µSec\u003c\/li\u003e\n  \u003cli\u003eLoad Cycles (min): 1%\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eReceiver\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSensitivity (10 dB S\/N, 3–80 Hz bandwidth): –86 dBm\u003c\/li\u003e\n  \u003cli\u003eClutter (3–80 Hz bandwidth): 10 µV\u003c\/li\u003e\n  \u003cli\u003eAntenna Gain: 8 dBi\u003c\/li\u003e\n  \u003cli\u003eVertical 3 dB Beamwidth: 36°\u003c\/li\u003e\n  \u003cli\u003eHorizontal 3 dB Beamwidth: 72°\u003c\/li\u003e\n  \u003cli\u003eWeight: 8 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Chip:\u003c\/strong\u003e HB100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 37 mm × 45 mm × 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e DC 5V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polymer housing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Quantities:\u003c\/strong\u003e 1 PC, 5 PCS, 10 PCS\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic door control systems\u003c\/li\u003e\n  \u003cli\u003eSecurity and surveillance systems\u003c\/li\u003e\n  \u003cli\u003eATM and automated video control\u003c\/li\u003e\n  \u003cli\u003eTrain and transit signal automation\u003c\/li\u003e\n  \u003cli\u003eDIY electronics and robotics projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eYou May Also Like\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/ccb-flat-round-spacer-beads-diy-jewelry-making\"\u003e4\/6mm CCB Flat Round Spacer Beads – DIY Jewelry Making\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/round-aluminum-wire-diy-jewelry-making-1mm-3mm\"\u003eRound Aluminum Wire 1mm–3mm | DIY Jewelry Making Wire\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.osha.gov\/eye-face-protection\" target=\"_blank\" rel=\"noopener\"\u003eOSHA on eye and face protection\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What is the HB100X Microwave Doppler Radar Motion Sensor Module used for?\u003c\/h4\u003e\n\u003cp\u003eA: The HB100X is a 10.525 GHz Doppler radar sensor module designed to detect moving objects without physical contact. It is widely used in automatic door controllers, security systems, ATM video automation, train signal systems, and custom DIY electronics projects. Its detection range extends beyond 20 meters, making it suitable for both short- and long-range motion sensing applications.\u003c\/p\u003e\n\u003ch4\u003eQ: What makes the HB100X better than infrared or ultrasonic motion sensors?\u003c\/h4\u003e\n\u003cp\u003eA: Unlike infrared sensors, the HB100X is not affected by temperature, lighting, humidity, or dust — making it far more reliable in harsh or variable environments. Compared to ultrasonic sensors, it offers a significantly longer detection range (20+ meters) and stronger resistance to RF interference, ensuring consistent performance in electrically noisy settings.\u003c\/p\u003e\n\u003ch4\u003eQ: What voltage does the HB100X module require to operate?\u003c\/h4\u003e\n\u003cp\u003eA: The HB100X operates on DC 5V (±0.25V), drawing a typical current of 37 mA in continuous wave mode. In pulse mode at 5% duty cycle, the average current drops to just 2 mA, making it highly efficient for battery-powered or low-power applications.\u003c\/p\u003e\n\u003ch4\u003eQ: How many units can I order at once?\u003c\/h4\u003e\n\u003cp\u003eA: The HB100X Motion Sensor Module is available in three quantity options: 1 PC, 5 PCS, or 10 PCS.
